That could be anything. Can you post a detailed Arnold log, so we can see your system specs, what's in the scene, how much memory is being used, and when the crash happens?
Does it always crash? What if you lower the AA to -3? That will at least make it faster to test.
Try enabling the Ignore features (Diagnostics), and then turn them back on, one by one, until you find where the crash happens.
